【摘要】 对EM中的酵母菌、放线菌和乳酸菌进行富集,并将其富集液和复合菌投加到黑臭河水中进行降解试验。结果表明,在好氧条件下,酵母菌和放线菌投加量分别为5%和8%时,反应2 d后,CODCr的去除率分别为47.2%和27.%;在自然静置条件下,乳酸菌的投加量为2%,反应6 d后,乳酸菌对CODCr的降解率可达56.9%,均比复合菌的去除效果好。酵母菌、乳酸菌对黑臭河水中的PO43-和NH3-N都没有降解能力。放线菌对黑臭河水中的PO43-和NH3-N有一定的降解能力,但效果不如复合菌。更多还原

【Abstract】 The experiment was mainly concentration to yeast,actinomyceto and lactobacillus in EM,then disposing the black and ordorous wastewater with concentration liquid and EM.Resullts showed that :under aerobic conditions,CODCr removal rate of yeast and actinomyceto could reach 47.2%、27.3% after 2 days,with 5%、8% addition respectively;6 days later,CODCr removal rate by lactobacillus reached 56.9% under natural conditions,with 2% addition.CODCr removal rate of them was better than that of EM.Yeast and lactobacillus had no degrading ability to PO43-and NH3-N in the wastewater.Actinomyceto had certain ability to PO43-and NH3-N,but was not better than EM.更多还原
